If you click the "Update Now" link on the Google home page, it will download an executable file – setgooglesearch.exe – on the desktop that will set Google as the default search engine inside IE.

Now Google regularly uses that space to advertise their other products but I think its the first time that they have placed a direct link to an .exe file on the homepage. And since its not mentioned anywhere that the link points to an executable, most people would only realize it once they have clicked the link.
